Resonating Exhaust - just me..?

[Kuro]

Hi folks

 

Lately my exhaust has been making some stange noises. In fact, ever since I Autosol'd it really - perhaps I have dislodged something..?

 

It's always resonated a bit, especially at high revs. But now I get an occasional 1600-1700 rpm resonance. (cold idle) It sounds like the system is just barely touching something metallic..?

 

Anyone else had this?

 

With the pants weather I've not had a chance to check the rear underside

mine does it but it's the raspiness of the hi-flow cats

 

could be touching some metal parts mate, only way is to put it on a ramp and rev it

Shouldn't do that mate

forgot to add: doesn't do it at low low revs as Kuro says, but when I cane it above 4500 revs. It's not really rasp, but you definitely hear the different tone of the exhaust

That's more like it

Your car revs above 4500 revs?

 

Not sure that mine does.... I'll have to try it
